docs: def C_wedge_meter_Miller(D, H):
      r'''Calculates the coefficient of discharge of an wedge flow meter
      used for measuring flow rate of fluid, based on the geometry of the 
      differential pressure flow meter.
      
      For half-inch lines:
          
      .. math::
          C = 0.7883 + 0.107(1 - \beta^2)
      
      For 1 to 1.5 inch lines:
          
      .. math::
          C = 0.6143 + 0.718(1 - \beta^2)
          
      For 1.5 to 24 inch lines:
          
      .. math::
          C = 0.5433 + 0.2453(1 - \beta^2)
          
      Parameters
      ----------
      D : float
          Upstream internal pipe diameter, [m]
      H : float
          Portion of the diameter of the clear segment of the pipe up to the 
          wedge blocking flow; the height of the pipe up to the wedge, [m]
          
      Returns
      -------
      C : float
          Coefficient of discharge of the wedge flow meter, [-]
  
      Notes
      -----
      There is an ISO standard being developed to cover wedge meters as of 2018.
      
      Wedge meters can have varying angles; 60 and 90 degree wedge meters have
      been reported. Tap locations 1 or 2 diameters (upstream and downstream),
      and 2D upstream/1D downstream have been used. Some wedges are sharp;
      some are smooth. [2]_ gives some experimental values.
